I loved this so much I practiced making it at home until I nailed it. For a long time I was addicted to this salad every time I went to Red Star and I love my meat and carbs. Za'atar is a Middle Eastern spice mix made mostly of thyme, sesame seeds and sumac (a dried fruit that comes from a shrub ). It can include Oregano, savory. I grew up eating bread with olive oil and dipped into Za'atar. They coat the chicken in this delicious spice mix and cook it and serve it over romaine lettuce. There are some good chunks of avocado, a bit of onion, cucumber, radish, and a touch of orange slices. A tahini vinaigrette ties this together perfectly. Tahini is made from ground toasted sesame seeds ground into a paste.
